Can you please help me investigate the issue I have with my package?
Yesterday it worked just fine. Not sure what’s changed.

Interesting find. That happened after the viewer publishing upload-deploy). If I delete the package on the datagrok side and then do upload-debug. It works just fine.

Thanks for reporting and for your observation as well - I think we now have a better idea of what went wrong. Looking into that.

Bump. I’m still having the issue.
But I found a workaround: when I upload a project and open it with a page reload) then it works just fine.
If then I close a chart and add it back then the issue happens again.

It’s not the convenient way to work with but at least something.
